Where is the body computer located in the Envision?
2 Answers
The body computer of the Envision is located above the accelerator pedal in front of the driver's seat, specifically on the left side under the center console. Functions of the onboard computer: The onboard computer is a specialized automotive information product designed for the unique operating environment and electrical circuit characteristics of vehicles. It features resistance to high temperatures, dust, and vibrations, and integrates seamlessly with the vehicle's electronic circuits. The onboard computer is typically used to calculate instantaneous fuel consumption, travel distance, temperature, average speed, average fuel consumption, etc. Some models also include functions like maintenance reminders and driver rest alerts. Vehicles equipped with onboard computers: Not all fuel-injected vehicles come with an onboard computer. While many modern vehicles have them, some may lack full functionality. Most contemporary vehicles are fuel-injected, and even older carburetor-equipped high-end models may have an onboard computer. Generally, the onboard computer is displayed on a small screen located on the dashboard or center console, providing various information.
I've been driving the Envision for several years. The body control module is usually located near the driver's seat footwell, hidden under the dashboard on the lower left side of the steering wheel. The position is quite concealed yet convenient for maintenance, as it controls electronic components like lights, door locks, and windows. If you want to find it yourself, first remove the floor mat, then take off the small plastic cover, and gently pry it open with a screwdriver. Make sure to disconnect the battery's negative terminal before working on it—otherwise, a short circuit could cause serious trouble. Last time when my car lights malfunctioned, I spent quite some time locating it, but it wasn't buried too deep, so even beginners can manage. The manual has diagrams, or you can check Buick's official website for documentation to be more precise—never force anything open and risk damaging the wiring.
